Specification of Letters Patent.

Patented Mar. 23,1915.

Application filed July 29, 1913. Serial No. 781,882;

To all whom it may concern Be it known that I, MAURICE HAYEs', a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Ash-Sifters, of which the following is a specification.

The primary object of my invention is the provision of an ash sifter, wherein the door of the casing is adapted to be moved to a prescribed'position, to serve as a chute to effect the discharge of the sifted material into a suitable receptacle, the construction of the casing and door being such as to pr0- vide a perfectly tight joint therebetween when the door is in its closed position.

Another object of the invention is the provision of a device of this character wherein the door of the casing is mounted for vertical swinging movement, and provided with a plurality of sockets, and means for interchangeably engaging in said sockets to hold .the door respectively in closed and adjusted positions. I

A urther object of the invention is the provision of a device of the abtive mentioned character, wherein a rotary sifter is employed, and means for preventing rotation ofthe sifter, when desired to facilitate the filling operation thereof.

A still further object of the invention is the provision of a device of the class in question which is simple in construction and which may be readily and easily manipulated for the purpose intended.

With these and other objects in view which will appear as the nature of the invention is better understood, the invention consists in the combination, detailed construction and arrangement of parts which are hereinafter more fully described and particularly pointed out in the appended claim.

In the drawing forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views; Figure 1 is a side view of the device with one wall removed to show the interior and working parts of the same. Fig. 2 is an opposite side view of the device showing the manner in which the cylinder is held against rotation. Fig. 3 is a sectional view taken on line 22 of Fig. 1. Fig. 4: is a perspective view of the rotary cylinder showing the manner of locking the cover thereof. Fig. 5 is a detail perspective view of the keeper plate. Fig. 6 isa detail perspective View of the lookingplate. Fig. 7 is'a detail sectional View of the handle. Fig. 3 1s a fragmentary sectional view of the slid ing door frame and cylinder showing the locking means for the door in side elevation. Fig. 9 is a similar view showingthe' locking" means in front elevation. Fig; 10' is a sectional view of the device showing the manner of locking the door of the" casing.

Referring to the drawings-by numerals 5' designates asubstantially rectangular bottoml'ess casing constructed from any suitable material and which when in use is supported by the open end of an'a'sh barrel or other suitable receptacle: The casing is provided with a cover 6 which is hinged to the casing as at 7 and with which any suitable means may be employed for retaining the same in locked position.

Arranged within the casing adjacent its upper end is a sifter 8 of cylindrical forma-' tion and' preferably constructed of wire netting. The sifter is adapted for rotation and is fixed upon; a shaft 9 which is jour'n'aled in the side walls of the" casing and extended from one side thereoftoprovide a handle 10 for turning the said shaft and'sifter. Journaled on the said shaft are the arms 11 of, the sliding door frame 12 which is covered with a suitable wire netting at 1 2. The sliding door controls an opening in the cylinder 8,fthe"opened position of the door being indicated by the dotted lines shown in Fig. 1.

For the purpose of locking the sliding door frame 12 both during the rotation of the cylinder, andwhen thesi'fted material is being discharged, I employ a leaf spring 5 which is secured at one end to the member 0 of the door frame was shown in Fig. 4c. The opposite end of the spring is formed with depending side flangescl and d which snugly embrace the opposite sides of the member 0 of the door frame andthe frame of the cylinder at one side of the opening thereof to retain the said sliding door in closed position, and adapted for engagement with the said frame at the opposite side of said opening to retain the said door locked; in open position when the sifted material is being discharged. The forward edge of the spring I) is formed with an upwardly projecting lip e by means of which the lock may be released when it is desired to move the door of the cylinder to open or closed position.

Extending from the front, rear and side walls of the casing and at the upper edge thereof are downwardly inclined partitions 13 and 13 which lead into the opening in the cylinder 8 and form a hopper to direct the unsifted material thereinto in the filling operation of the cylinder. The front wall of the casing is cut away to provide a relatively large door opening, which is normally closed by a door 14L which may be swung to a position within the casing for a purpose which will hereinafter be described. Arranged immediately below and to one side of the cylinder 8 and mounted in the side walls of the casing is a shaft 15 upon which the door 14 is pivotally mounted by means of substantially ii-shaped brackets which have their arms 17 and 18 secured to the side edges of the door and their vertexes journaled on the said shaft 15. By reason of this construction and arrangement the door is capable of being swung within the casing to assume a diagonal position therein as indicated by dotted lines in Fig. 1, whereby the door 1a cooperates with the stationary downwardly inclined shelf 19 to provide a slide or chute by means of which the shifted material is delivered from the cylinder into any suitable receptacle. The lower end of the door 14; is spaced a suflicient distance from the shelf 19 to allow free passage of the door when the same is swung to its adjusted position within the casing, a piece of sheet metal 191 being secured to the top of the shelf and projecting beyond the free edge thereof so as to serve as a stop for the door and cover the joint or space therebetween and said shelf.

The upper and lower edges 20 and 21 of the door 14 are beveled to correspond with the beveled portions 22 and 23 of the door opening whereby a perfectly tight joint is provided between the said door and casing when the former is arranged in its normal or closed position. The lower rail '24 of the front wall of the casing has its upper front edge beveled in an opposite direction from the beveled portion 23 and extended slightly above the beveled portion 23 so that the upper portion of the door will be properly supported in alinement with the stationary shelf 19 when the door is swung to its adjusted position to serve as a slide or chute for the purpose hereinabove set forth.

In order to lock the door 14 against movement when in its normal or adjusted position ll employ a leaf spring A which is vertically disposed and secured at its upper end in any suitable manner to one of the side walls of the casing adjacent the lower end thereof. Adjacent its lower end the spring has secured thereto by means of a set screw a a locking pin B which projects through a suitable opening within the casing. @ne of the side edges of the door is provided with an upper and lower socket g and g which are adapted to register with the said opening in the casing for the reception of the locking pin B. These sockets are so arranged that when the door is in its adjusted position the socket g occupies the same position as the socket 9 when the door is in its normal or closed position, and by reason of which fact it is manifest that one of the said sockets is always engaged by the looking pin B in the manner shown in Fig. & whereby the door as above stated is locked against movement in either its open or closed position. The lower end of the spring is curved outwardly from the wall of the casing to provide a lip, by means of which the pin B may be disengaged from the sockets to permit of the movement of the door as described.

Secured to the inner surface of the upper portion of the front wall of the casing is a panel 25 which extends a considerable distance below the axis of the cylinder 8 to partially close the door opening of the easing and to prevent undue scattering of the sifted material when the door is used as a slide or chute to effect the discharge of the same.

lVith a View of locking the cylinder against rotation to facilitate the filling operation thereof, 1 provide means whereby the handle 10 is locked to one of the side walls of the casing, and which may be readily and easily released therefrom. The said means comprises a keeper 25 which is formed with a groove 26 for the reception of the locking plate 27 which will presently be described, and a depending apertured end flange 28 for securing the said keeper to the casing slightly below said handle. The handle has its surface adjacent the casing provided with a longitudinally extending groove or recess 29 opening at one end thereof and adapted to slidably receive the locking plate 27. The said plate 27 is substantially flat and has a centrally disposed elongated slot 30 which receives a guide pin 31 that projects from the rear wall of the said recess 29 of the handle, and limits the sliding movement of the plate. Above and below the elongated slot 30, the plate is formed with curved offsets 32 and 33 which alternately engage the recesses 34 and 35 in the rear wall of the recess 39 of the handle to retain the said plate in an out of locking engagement with the keeper 25. The plate is twisted as at 36 to provide an angularly disposed lower end portion 37 which is arranged below and in alinement with said handle and adapted to be moved into and out of locking engagement with the said groove 26 of the keeper plate 25 by means of a manipulating flange 38 formed by the upper end of said plate for the purpose hereinabove set forth.

In using the device the handle is turned and locked in the manner hereinabove described in proper position so as to retain the opening in the cylinder 8 uppermost, the cover 6 of the casing is then raised and the sliding door of the cylinder moved to opened position as indicated by dotted lines in Fig. 1. The unsifted material is then poured into the cylinder, after which the sliding door thereof is then closed and locked in the manner hereinabove described as is also the door 6 of the casing. The handle 10 is then unlocked, and turned thus imparting a rotary movement to the cylinder 8 by which the material is thoroughly and quickly sifted. The door 14: is then unlocked and swung upon its shaft by means of the brackets 16 to the position indicated by dotted lines in Fig. 1, in which position it is then locked and cooperates with the shelf 19 to form a slide or chute for effecting the delivery of the sifted material into a suitable receptacle which may be positioned adjacent the casing. The handle is then turned to cause the opening of the cylinder to again be arranged uppermost, after which the sliding door thereof is moved to an open position and locked in the manner hereinabove described. The cylinder is then again rotated to discharge the sifted material therefrom. The door 14: is then unlocked and moved to its normal or closed position and the operation again repeated when desired.

From the foregoing description taken in connection with the accompanying drawing it is obvious that I have provided a device A device of the class described comprisv ing a casing having an opening in one wall thereof, a rotary sieve mounted therein, an adjustable door controlling said opening,

and means carried by the door for pivotalconnection with the casing at a point in a plane approximately midway between the ends of the door and within the casing, whereby said door may be swung to adjusted position wholly within the casing to form a chute.

In testimony whereof I affix my signature in presence of two witnesses.
